INKSTAND.

SPECIFICATION forming part of Letters Patent No. 650,046, dated May 22,1900.

Application filed August 25, 1898. Serial No. 689,466. (No modelJ ToaZZ'whom it may concern.-

Be it known that I, PETER D. HORTON, a citizen of the United States ofAmerica, re siding in the city of Oakland, county of Alameda, and Stateof California, have invented certain new and useful Improvements inInkstands, of which the following is a specification. Y

My invention relates to improvements made in reservoir-inkstands; andthe same consists in certain novel parts and combination of parts, ashereinafter described and claimed and as illustrated in the accompanyingdrawings, forming part of this specification.

Figure 1 of the drawings is a longitudinal section in perspective ofaninkstand constructed in accordance with my said invention. Fig. 2 is aplan or top view of a con struction in which the inkstand is providedwith a sponge-cup and a water-reservoir in addition to the ink-Well andits fountain or reservoir. Fig. 3 is a longitudinal section through theink-reservoir and the elastic top. Fig. 3 is a sectional view of theelastic top removed from the reservoir. Fig. 4 is a sectional View ofthe feed-tube removed from the reservoir. I

A indicates the body of the inkstand, and A a well or cup in the top ofrelatively-small size to contain ink in sufficient quantity for chargingthe pen-point when the same is dipped into the cup.

A is a Well or receptacle to contain a body of ink and forming areservoir for supplying the well A.

The tops of the two receptacles A A are on the same level, but thebottom of the larger one is situated below the bottom of the smallerone.

B is a flexible tube having one end 17* resting on or set in closeproximity to the bottom of the reservoir A and the other end b insertedthrough the wall or partition that separates the receptacle A from thereservoir. That end of the tube which is set through the partition isfixed in place at suflicient height from the bottom of the receptacle Ato provide a proper depth of ink or fluid in the receptacle, thefunction of thetube being such that it acts both as a supply-passage forthe ink or fluid from the reservoir and as an overflowpassage throughwhich any excess of fluid above that point will flow back into thereservoir, thereby preventing the contents of the well from overflowingor from exceeding a given depth.

The reservoir A is closed by a top or cover 0, constructed with a heavyflange O, which flts tightly into the reservoir, and a projecting rim Gwhich makes a close fit against the flat margin surrounding thereservoir and in connection with the tight] y-fitting flange insures anair-tight joint between the stand or body containing the reservoir andthe cover. The central portion 0 is made thinner or more flexible thanthe body of the cover at the surrounding flange, and the flange C ismade somewhat larger in diameter than the reservoir A so that whenplaced in the opening and pressed down into place the cover will closethe top; but the compression of the flange will cause the more flexiblecenter portion 0 to assume an arched or crown-like form, by virtue ofwhich that part will both readily yield to pressure applied from aboveand will return to position again as soon as the pressure is removed.

D is an air-vent in the cover 0, through which pressure of theatmosphere is admitted to the reservoir and an equilibrium between theexterior atmosphere and the interior space of the reservoir above thefluid contents is es tablished.

The operation of transferring the ink or fluid from the reservoir to theWell A through out of rubber and the tube B can be made of the samematerial or substance. If metal be substituted for rubber, care shouldbe taken to secure an airtight joint between the cover and the rim ofthe reservoir. in that case will be suitably bent to turn its lower endperpendicularly downward against the bottom of the reservoir. The lowerend The metal tube portion of the tube is-slittedor cutaway oli preventthe end-from being choked or cl9gged with the heavy or thicker portionof the contents at the bottom ofthe receptacle. 7

a construction of reservoir-inkstand in which on :eithersideof thesmaller receptacles Having thus fully described :my invention,

what 1 claim as new therein, and desire to secure by Letters Patent, is-

bo'dyrhaving an ink-reservoir, a detachedwe'll located oiitside of thereservoir, the bottom of said-well bein g situated above the bottom.ofthe reservoir, a flexible tubeopen at both ends :and "having itslower end in proximity I .to the bottom of the reservoir and its upperend .terminatingTin the wellabove tlie'bottom thereof, and Yacover'adaptedto, close the top "haying a broad and solid circular-flangeon the bottom fitting the opening, and an elasticidepressiblevcenterportion having a vent- In Fig. 2 of the drawings Ihave illustrated:

The combination, with the bodyA having an open-top reservoir A and awell A of smaller capacity, the bottom of the well being situated abovethe bottom of the reservoira-nd' located .exteriorly thereof, and theflexible tube connecting the reservoir and the well; of the covercomprising the disk 0 havbottom of somewhat greater-diameter than thereservoir-opening, to .fit therein under compression, and an elastic anddepressi-ble a vent-hole.

In testimony that I .claim the foregoing I have hereunto set'my hand andseal.
